Abstract

Et stempel, frem- og tilbakebevegelig i en sylinder, er avtettet mot sylinderveggen ved hjelp av fluid av et trykk som er høyere enn trykket av fluidene på de motsatte sider av stempelet, som fremføres til ringrommet (18) mellom to tetninger (19,20) som er virksomme mellom stempelet og sylinderveggen, og hvor det er anordnet en akkumulator eller et hjelpeforsterkerkammer (67) hvorfra overtrykksfluid overføres til ringrommet mellom de to tet- ninger, for regulering av trykket mellom disse. De to tet- ninger mellom stempelet og sylinderveggen kan bestå av henholdsvis første (19A-19C) og andre (20A-20C) grupper eller antall av separate tetningsringer som, vedrørende materialet og dimensjoner, er utvalgt for gjennomføring av spesielle funksjoner. Videre kan et tetningssystem mellom et stempel og en sylinder hvori stempelet er frem- og til- bakebevegelig, omfatte en fremre tetning (19,20), fortrinnsvis med to tetninger eller tetningsring-grupper som beskrevet, som atskiller et prosess- eller drivfluid (4) som holdes i bevegelse av stempelet, fra et andre fluid (7) i ringrommet rundt stempelet, og en atskilt og baken- forliggende sperretetning (21A-21C) atskiller det andre fluid fra et tredje fluid som fyller et ytterhus (6) med en innmontert motor for drift av stempelet.A piston, reciprocally movable in a cylinder, is sealed to the cylinder wall by a fluid higher than the pressure of the fluids on the opposite sides of the piston, which is fed to the annulus (18) between two seals (19,20 ) operating between the piston and the cylinder wall, and where an accumulator or auxiliary amplifier chamber (67) is provided, from which excess pressure fluid is transferred to the annulus between the two seals, to regulate the pressure between them. The two seals between the piston and the cylinder wall may consist of first (19A-19C) and second (20A-20C) groups, respectively, or the number of separate sealing rings, which, with respect to the material and dimensions, are selected for carrying out special functions. Furthermore, a sealing system between a piston and a cylinder in which the piston is reciprocated can comprise a front seal (19,20), preferably with two seals or sealing ring groups as described, which separate a process or propellant fluid (4). ) held in motion of the piston, from a second fluid (7) in the annular space around the piston, and a separated and trailing latching seal (21A-21C) separates the second fluid from a third fluid which fills an outer housing (6) with a mounted motor for operation of the piston.
